Switch;
If using batteries, insert them as
shown:
Never turn this switch off. Doing
so causes you to lose all informa-
tion you have stored in the
Tandy 102.
2. Supply electric or battery
power:
If using electricity, connect the
Tandy 102 to an electric outlet,
using the Tandy 102 power
adapter. [Use only the Tandy 102
power adapter!)
3- Turn on the Power Switch,
and adjust the DJSP dial to your

the Tandy I02's read-only
memory (ROM) and will remain
in memory permanently.
The remaining spaces are empty

Keeping Information Safe in
Memory
The nest chapters show how to
store information in the Tandy

terna] battery keeps this informa-
tion in RAM even when the
power is off. Make sure this in-
ternal battery never dies:
6/Starting Up

Never [Urn off the Memory
Switch on ihe bottom of the
Tandy 302, This turns off the
internal battery. We suggest
that you put tape over this
switch so nobody turns if off:

•If you need to let the
Tandy 102 sit idle for more
thati 5-15 dayi, be sutc that
it has batteries in it and
thai these batteries are run
dead. The Tandy 102\
interna] battery needs some
kind of power source so
that it can keep itself
charged.
Using a Printer
•Vote; If you do not have a
printer, skip to the next chapter.
You can use most any Radio
Shack "parallel'' printer with the
Tandy 102. To connect it, you
need to purchase the Tandy 102
printer cable (Cat, No, 26-1409).
Unpack your printer. Refer to
